Description

Tooth brush having reinforcement

The present invention relates to a toothbrush, and more particularly to a toothbrush of the bristle reinforcement structure to adjust the elasticity of the bristles to enhance the cleaning function while preventing deformation to improve durability.

Toothbrushes that are treated every day in everyday life are relatively inexpensive and are so common household items, but it cannot be denied that they are an important tool for protecting the teeth, which are recognized as one of the five traditional clothing.

Handles, heads, and bristles, which are the main components of toothbrushes, are developed and marketed in various forms to improve cleaning functions in connection with the structure of the oral cavity. Among them, bristles are directly contacting teeth and gums, and the introduction of structures and materials to prevent deformation while being flexible is being actively conducted.

However, in the case of users who are poor at brushing such as children and the elderly, no matter how expensive toothbrushes are used, the bristles are spread outwards and can not be used quickly, and since they are not replaced at the appropriate time, the cleaning function is not properly exerted, which leads to the neglect of tooth damage. do.

Accordingly, an object of the present invention is to provide a toothbrush having a bristle reinforcement structure to prevent the deformation and to improve the durability by adjusting the elasticity of the bristles to prevent the deformation while enhancing the cleaning function.

To achieve this purpose, the present invention is a toothbrush consisting of a handle 10, a head 20, the bristles 30: to prevent deformation by increasing the elasticity of the tip portion in contact with the teeth in the bristle 30 It characterized in that it comprises a reinforcing means for wrapping the stop or lower portion in a predetermined unit.

As a first embodiment of the present invention, the reinforcing means is used as an integral structure of the tube 40 and the base plate 45 attached to the head 20 to wrap the bristles 30 to the same height by a predetermined amount.

As a second embodiment of the present invention, the reinforcement means uses a tube 40 attached to the head 20 to wrap the bristles 30 to the same height by a predetermined amount, or differential the bristles 30 by a predetermined quantity. A tube 40 attached to the head 20 is used to wrap to one height.

As a third embodiment of the present invention, the reinforcing means uses a porous plate 60 installed in a lattice structure to space the bristles 30 by a predetermined amount.

Accordingly, in the related art, the stiff bristles 30 have a high risk of damaging teeth and gums. However, if the structure of the present invention is used, very soft bristles 30 can be used like wool, so that the elderly, children, and patients with physical beauty may suffer. Even if it is, the function of washing and durability is excellent.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment according to the present invention.

The present invention is a toothbrush consisting of the handle 10, the head 20, the bristles 30, the stop or the lower end portion to increase the elasticity of the tip portion in contact with the teeth in the bristle 30 to prevent deformation It includes reinforcing means wrapped in a unit. The bristle 30 is a configuration in which the unit is bundled by a predetermined number is arranged at a predetermined interval on the head 20, and is divided into a lower portion, a stop portion, a tip portion close to the head 20.

1 is a perspective view showing the main portion of the toothbrush according to the first embodiment of the present invention.

As can be seen from the exploded perspective view of the main part in Figure 1 and the enlarged configuration diagram, the reinforcing means of the present invention by the integral structure of the tube 40 and the base plate 45 attached to the head 20 To brush the bristle 30 to the same height by a certain amount. A tube 40 for enclosing the bristle 30 of the unit body is integrally formed on the base plate 45, and the base plate 45 is attached to the head 20, and then the bristle 30 is bonded to the finished toothbrush. Is generated.

Figure 2 is a perspective view showing the main portion of the toothbrush according to the second embodiment of the present invention, Figure 3 is a perspective view showing the main portion of the toothbrush according to the modification of FIG.

In Figure 2, the reinforcement means of the present invention uses a tube 40 attached to the head 20 to wrap the bristles 30 to the same height by a certain amount. The tube 40 is bonded onto the head 20 while wrapping the unit of the bristles 30 at the same height (or length) ℓ, respectively, to reinforce the elasticity of the tip of the bristles 30. The tube 40 uses the same material as the bristle 30 or another material similar in elasticity to the bristle 30. If the elasticity of the tube 40 is relatively weak, the height l extends to the stop of the bristles 30, and conversely, if the elasticity is relatively strong, the height l is limited to the lower end of the bristles 30.

In FIG. 3, the tube 40, which is a reinforcing means of the present invention, may be attached to the head 20 so as to wrap the bristles 30 at a predetermined height by a predetermined amount. As shown, the height of the tube 40 is constantly reduced in the order of l ₁ , l ₂ , l ₃ and arranged again to repeat in the same manner. This may be applied to correspond to when the height of the bristle 30 is different, or may be applied to the case where the height of the bristle 30 is the same. In either case, the bristle 30 has various elasticities, so it is suitable for a special use.

As the height (l) of the tube 40 is higher, the flexibility of the bristles 30 is reduced, so that even when the bristles 30 of a softer material than before are used, the phenomenon in which the tip ends out after short-term use is prevented.

In this case, in some cases, the above-described configuration of FIGS. 2 and 3 may be combined. For example, two rows (outermost and bottom row in the illustration) on the outside of the head 20 make the tubes 40 the same, while the remaining inner rows make the tubes 40 different. Increasing the height of the tube 40 at the tip of the head 20 is advantageous for raising the toothbrush to clean the molars.

The tube 40 of the present invention has a circular band 40a formed on the outer circumferential surface so as to be in intimate contact with the head 20. The circular strip 40a is injection molded in a unitary configuration with the tube 40, and enhances the aesthetics of the appearance while reinforcing the elastic force of the tube 40. It is also possible to shape the strip of the square instead of the circular strip 40a.

On the other hand, in the configuration of Figure 1 can be configured to differentiate the height of the tube 40 as shown in FIG.

FIG. 4 is a schematic view showing a state in which FIG. 2 and FIG. 3 are specifically implemented, and FIG. 5 is a diagram illustrating a method of joining the tube of FIG. 4.

In FIG. 4, the tube 40 according to the present invention maintains an inclination angle α or β that is inward or outward as needed. In joining the tube 40 on the head 20, FIG. 4A is arranged to stand upright, FIG. 4B is arranged to be inward at a constant inclination angle α, and FIG. 4C is at a constant inclination angle β. It is arranged to face outward. Inward and outward directions are divided based on the center line in the longitudinal direction connecting the handle 10 and the head 20. The figure shown to the right in FIGS. 4A-4C is a side view observed from the center line direction (the longitudinal direction of the toothbrush), respectively.

Inwardly, the bristles 30 and the tube 40 are advantageous in terms of preventing the bristles 30 from spreading outward. On the other hand, outwardly brushing the bristle 30 and the tube 40 is advantageous in special cases, for example, in cleaning a large area or removing calculus in a powered toothbrush having a relatively low total number of bristles 30.

In FIG. 5, two ways of forming the inclination angle α (β) of the bristles 30 and the tube 40 are proposed. As shown in FIG. 5A, the inclined surface 40a is formed at the bottom of the tube 40 to be joined to the insertion hole 20a of the head 20, or as shown in FIG. 5B, the insertion hole 20a having the inclined surface is formed in the head 20. The ordinary tube 40 is joined. In any case, the circular band 40a is formed at the same inclination angle α (β) to be in close contact with the head 20.

On the other hand, the height (l ₁ , l ₂ , l ₃ ) and the inclination angle (α) (β) of the above-described tube 40 is merely exaggerated for clarity, and in practice, the fluctuation of the dimensions need to be very large. none.

FIG. 6 is a schematic view showing main parts of a toothbrush according to still another modification of FIG. 2, and FIG. 7 is a schematic view illustrating a state in which FIG. 6 is specifically implemented.

As a variant of the present invention, it is also possible to use a connecting table 50 that is continuously or discontinuously coupled between the neighboring tubes 40. This is an alternative to giving the inclination angle α (β) to the tube 40 as shown in Figures 4 and 5, Figures 6a to 6c respectively correspond to Figures 4a to 4c.

In FIG. 6, the connecting rod 50 is integrally injection molded using the same material as the tube 40. The cross-sectional area and the joint position of the connecting table 50 are determined in consideration of the strength that the material allows. After that, the required length of the connecting rod 50 is calculated so that the tube 40 is disposed at an upright or set inclination angle α or β.

Of course, the connecting table 50 may be injection molded separately and forcibly fitted to the tube 40. In this case, it is possible to form a thinner than the tube 40 by using a material that is harder, but the manufacturing labor due to the coupling to the tube 40 is increased.

In FIG. 7A, the connecting rod 50 is disposed parallel to the central axis connecting the handle 10 and the head 20. The column of symbol C illustrates that the connecting rod 50 is continuously coupled between neighboring tubes 40, and the column of symbol D indicates that the connecting rod 50 is discontinuously coupled every pair of tubes 40. To illustrate. Of course, although not shown, a configuration in which the connecting table 50 is arranged in a direction orthogonal thereto is also possible.

In FIG. 7B, the connecting rod 50 is illustrated in a triangular form with three neighboring tubes 40. This is appropriate for electric toothbrushes that have a circular head rather than a regular toothbrush.

8 is an enlarged perspective view of the tube of FIGS. 1 to 7.

The tube 40 of the present invention includes a plurality of through holes 40a for discharging water and foreign matter interposed in the inner space. The larger the space between the bristles 30 and the tube 40 of the unit unit weaved by a certain amount, the larger the length of the tube 40 is, the more easily water and foreign substances are introduced into the internal space. If this condition persists for a long time, bacteria may grow, thereby forming an appropriate size and number of through holes 40a on the tube 40 as a whole. In particular, the size of the through hole 40a is an important factor in design for implementing such a function. If the size of the through hole 40a is too small, water may not be smoothly discharged by surface tension, and if the size of the through hole 40a is too large, the strength of the tube 40 may be reduced. .

In addition, the upper end of the tube 40 is rounded so that the discomfort coming in contact with the gum is alleviated.

On the other hand, through the embodiment of the present invention proposes a configuration in which the tube 40 is bonded to the head 20, it is also possible to simply insert the tube 40 without bonding. Accordingly, the tube 40 is moved up and down on the bristles 30 and is convenient to discharge the water and foreign matter, so the size and quantity of the through hole 40a may be reduced or omitted at all.

In addition, although not illustrated in the drawings as another embodiment of the present invention, the elastic force may be doubled by forming the unit material of the tube 40 into soft and hard.

In addition, instead of accommodating a plurality of bristles 30, that is, a unit, the tube 40 of the present invention may accommodate one bristle 30.

Figure 9 is a perspective view showing the main portion of the toothbrush according to the third embodiment of the present invention.

As a third embodiment of the present invention, the reinforcing means uses a porous plate 60 installed in a lattice structure to space the bristles 30 by a predetermined amount. The porous plate 60 is formed in a lattice honeycomb form by removing all portions except the periphery of the plurality of through holes 60a for accommodating the bristles 30 unit. The through hole 40a is sized to properly tighten the bristles 30 unit to prevent the easily detached. Initial use of the toothbrush while lowering the perforated plate 60 close to the head 20 to be used gradually up so that the upper end of the bristles 30 does not open.

Even when using such a porous plate 60, it is possible to adjust the inclination angle α (β) like the tube 40. Unlike the tube 40, the absence of water or foreign matter remains an advantage.

10 is a perspective view illustrating a main portion of the toothbrush according to the modification of FIG. 9.

As can be seen from the state in which the main part is disassembled and shown, the above-mentioned porous plate 60 is connected through the base plate 70 and the support base 65. The base plate 70 is provided with the through hole 70a at the same position as the porous plate 60. The support base 65 connects the porous plate 60 and the base plate 70 to the same height in two or four places. Accordingly, the base plate 70 is bonded to the head 20, and then the bristles 30 are bonded to complete the product.

This configuration is advantageous to prevent the separation of the porous plate 60 by adding a separate support (65) in case the child pulls out the porous plate 60 for fun.

According to the structure of the present invention described above, the left and right bends and the up and down bending of the bristles 30 can be brushed with a cushion, and elasticity is restored immediately to prevent deformation, so the purchase time of the toothbrush is longer and economical.

According to the above configuration and action toothbrush of the bristle reinforcement structure of the present invention has the effect of improving the durability by preventing the deformation while enhancing the cleaning function by adjusting the elasticity of the bristles.

It is apparent to those skilled in the art that the present invention is not limited to the embodiments described, and that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or modifications will have to belong to the utility model registration claims of the present invention.
